I don't know what is it but every time I try to log in on the new launcher it won't work. I click on Minecraft it brings up the launcher then I press play and just says preparing at the left hand side and it shows no progress i've tried leaving it there for 10 to 20 mins and it still won't work its very frustrating to have to download the old launcher every time I wan't to play Minecraft and its probably not good for my computer either please try your best to fix this bug i understand all the work you do and I appreciate it thank you
